President Donald Trump and CEO of Twitter Jack Dorsey met in the Oval Office Tuesday to discuss apparent bias on the platform amid reports that Twitter employees who lean conservative don’t feel comfortable in the workplace.

In a statement, a Twitter spokesperson said, “Jack had a constructive meeting with the President of the United States today at the president’s invitation. They discussed Twitter’s commitment to protecting the health of the public conversation ahead of the 2020 U.S. elections and efforts underway to respond to the opioid crisis.”

Among others in the room, Trump was accompanied by Dan Scavino, the White House director of social media and a longtime Trump aide who frequently posts for him on Twitter. Dorsey was accompanied by Vijaya Gadde, Twitter’s head of legal, policy, and trust & safety.

For years prominent Republicans and right-wing media personalities have repeatedly made unfounded accusations that Twitter and other social media platforms are biased against conservative users.

The meeting comes amid reports, from Dorsey himself, that Twitter does lean to the left and even conservative employees don’t feel “safe” expressing their political opinions.

Twitter CEO Jack Dorsey says in a new interview that his company’s conservative employees are afraid to express their opinions.

“We have a lot of conservative-leaning folks in the company as well, and to be honest, they don’t feel safe to express their opinions at the company,” Dorsey told Recode in an interview published Friday.

“They do feel silenced by just the general swirl of what they perceive to be the broader percentage of leanings within the company, and I don’t think that’s fair or right,” he added, though he did not specify to what extent or how many of Twitter’s conservative employees felt unable to voice their opinions.

“We should make sure that everyone feels safe to express themselves within the company, no matter where they come from and what their background is,” he said.

Many conservatives who use the site have complained for many months that their accounts were being restricted — or “shadowbanned” — to keep their content from reaching a broad audience.
